Hi guys,
Please bear with me as I've never owned an Android phone before.
I have a Samsung Galaxy S4 I9505 and last week, it started having major battery drain of around 4%-5% per hour of idle screen-off time. This was much more severe than it was in the first two weeks of ownership, which was only about 1% or less an hour. Unfortunately, I have not been able to fix this issue.
I had heard about wake locks in Android, so I downloaded the app Wake Lock Detector and ran it a few days ago. It seemed from the analysis that by far the biggest consumer of my battery was a "com.sec.app.clockpackage". Here is the screenshot I took from the app a few days ago.
tinypic.com/view.php?pic=qzhohx&s=5
I tried googling this and it seems related to the alarm clock???!!! However, I couldn't find anything to help solve my problem. Even after I turned off the alarm clock and deleted all alarms set nothing would solve the problem.
The problem persisted and I decided a few hours ago after having the problem for half a week to factory reset the phone, thinking that I had some rogue application. After resetting the phone, I immediately installed Wake Lock Detector and nothing else.
However, that did not solve the problem. This is another screenshot I took from the app just a while ago.
tinypic.com/view.php?pic=20rx9f&s=5
If you would note, once again com.sec.app.clockpackage is dominating the partial wake lock list.
Could anyone please help me with this - How come a factory reset did not help restore it to how it was when I first bought it, when I didn't have this issue of draining 5% battery per hour? One thing I have noticed is the number of wake locks for com.sec.app.clockpackage is approximately the same in number as com.sec.phone, although that process takes up far less time overall.
Would anyone be able to help me out? I don't know much about these technical things. Many thanks!

Hi,
I have the same problem. Not with the clock but after 2 weeks it started to have major battery drain. i don't know what to do in order to solve this.
Hi bbbb2004, it seems like no one has been able to help us so far.
However, did you also initially have no problems with the battery and it only started getting worse a few weeks in?
Maybe you could also try Wake Lock Detector to try to find out what the cause is. From the pics I posted, I found out what the cause is on paper, but I have no idea what it actually is...

I did try Wake Lock and saw the problem: 1. exchange service 2. com.facebook.katana and third place is facebook messenger. Initially, when i bought the phone i had no problems but after 2 weeks it started to get worse. Interesting thing is that now is going down like 12-15% / hour almost without any usage and the phone gets really hot in the camera area.
Today the phone died while the battery was at 43%. The left corner led was blinking blue and no button was working. The only thing i could do to start was to remove the battery and put it back.
Been quite a while and the problem still hasn't resolved itself. On a daily basis, I can get up to one hour of wake lock from the reading on Wake Lock Detector and GSam battery monitor. (and they show exactly the same time)
I have however gotten a bit closer to trying to solve the issue. The wake lock seems to clock much more faster at my house than when I'm outside. If I'm out all day, I can come back with only around 3-5 minutes of wake lock from com.sec.app.clockpackage. It still accumulates over time, but at a substantially lower rate.
I have no alarms set.
The only thing I can think of is that reception at my house is not superb, and does fluctuate based on the indicator bars shown on the phone. However, I don't think that fluctuating reception can cause a wake lock for com.sec.app.clockpackage, which is something to do with clocks presumably.
Anyone have any other ideas?

Try turning off your email sync and facebook apps. If it still happens, you could try a factory reset or reflashing the firmware. Sometimes its just a bad s/w write and a factory reset could fix that.

When my phone is sitting idle (screen off) it will randomly decide to power itself off. Has anyone else noticed this? Any ideas on what could be causing it?

you mean randomly power itself ON, right?
if that is the case, it's normal, it just mean it woke up to connect to the internet, to get updates of news, emails, or whatever it was scheduled to pick up
nope. i mean it randomly turns itself off. this topic is being discussed over on the att captivate galaxy forum section.
interesting, so it's going from stanby mode, to complete OFF... nope never seen that happen to my i9000 model
yep totally powered off... completely sucks... looks like there are a bunch of ppl that have this issue with the captivate on att. $10 says its some lame piece of software that att puts on your phone that's causing the problem.
it's possible, i've read here a few users having crazy power issues (battery draining very fast) with their SGS i9000, but after wiping it out clean, to start anew, then the power problem is gone away.
so yes, a software could cause something weird like that.
Factory reset and so far so good
Hey guys,
I use a Galaxy S here in Hong Kong and I had the same random shut down issue constantly happen when my screen went off...
I tried everything, check temperature of cpu, etc. etc. and nothing worked, it just got worse and worse.
I even changed the battery to use the spare one that came with this. Still problematic.
Used SET CPU to limit the cpu to 400mhz, still problems.
Finally I did a factory reset and so far so good.
I only have the original system installed with the Remember the Milk app installed.
24 hours, no problems.
Installed AppBrain app.
Then I installed 3G WatchDog
12 hours, no problem.
Then I installed Paperdroid
12 hours, so far no problems at all.
If I run into an issue I'll post it here. But I think it definitely was a software issue.
Update - it randomly shut down on me
Alright guys, it shut down on my randomly today in the afternoon......
I dont know if it's the re-charging that screwed it up?
Because after my factory reset, last night was the first time i charged it....
Hmmm
This happened to me too - two days in a row until noon it would shut down two or three times - i uninstalled SetCpu and for now (24 hours) it hasn't happened again. I am not sure if it was the one responsible but it started happening after i installed two programs and i uninstalled them after it started happening. I uninstalled Visual Task Switcher first but on the next day it turned off again, then i unsinstalled SetCpu and it hasn't happened again - maybe some wrong profile settings but i didn't feel like experimenting
I had this issue once too in about 40 days.
I was reading an sms and then i turned into standby and put it in my pocket. Later, maybe 40 minutes i came home and my phone was completely off. I do not remember if i had to take out the battery before to get it on again.
I was wondering why it happened. Maybe it was caused by an app i had opened. Battery still was at 40%.
But since it only occured once in 40 days i doesn´t bother me.
Interesting you mention this as it just happened to me today for the first time. I took it out of my pocket and wtf? The phone was off. Very strange... Using the i9000 on the stock Eclair rom.
Should send back for warranty

software clash?
Well the phone suddenly switched off for me, but this time I turned off APPBRAIN and so far so good.
In fact, I came across an app called NoLED and since it kind of keeps ht phone on, while I have it on my desk, I'm able to be notified of stuff and so far with that, the phone hasnt' shut off.
I'm still experimenting with what works, but try turning off AppBrain and see if you still have the random shut off issue....
i use app brain all the time to keep my apps in sync
not the cause of the problem, that's for sure
my phone can last a whole day even with app brain running
OP, do you have MSN Talk installed on your phone? I have this same problem, seems to happen more when I am running MSN talk in a low signal area.
«try a new sim card. «Could be faulty. «i am on my 3rd phone and all of them had this same problem. «i bought a new sim card 4 days ago, and hasnt happened since. «but then again, this problem usually happens to me once every 3rd-5th day anyways, so i dont know if i am in the clear yet.
Me too, shutdown everyday
Hi guys
After upgrade OS to I9000ZSJG4, Phone random shutdown everyday.
Yep still shuts down
Tried keeping AppBrain off, still shuts down.
Used NoLED so the screen kind of stays on, still shuts off..
So far shut off on me after 40 hrs... this is really stupid.
I am this close to taking it back, but I genuinely think it's a software issue than a hardware issue...sigh
Anyone have any luck figuring this out?
Same problem no solution yet
Hi
I too have the same problem, haven't found any solution yet.
The temperature etc is all good, there is no pattern in shutdown issues.
I have tried factory reset and no new application, it still shut down while using in built browser.
I had the same thing happen to me while skiing in Whistler last weekend. It died twice. I attributed it to the cold. I normally use a 3000mah battery up there, but left it back the house that day. Afterwards while charging in the car and even charging it at home it died prematurely again. It was the eBay aftermarket variety 1500mah knock off. I have since changed back to the Samsung OEM battery. I haven't had an issue with it since. My assumption is that the knock offs in my case cannot handle the heat cycles of charging and then the cold as well as the original. Or they have a limited lifespan, well below OEM specs. I am now only using the 3000mah battery on the weekends to hedge my bet on the quality of manufacture, as it seems to be from the same factory as the 1500.
Recently I have noticed on several occasions that my phone have gotten hot and started eating away the battery. One time I had around 30% battery and the phone was laying in my pocket. I felt the heat through the pockets and took it up to see what's up. It then had 0% battery and turned itself off.
When looking at battery use in settings, it's hard to pick out one specific application that might do this. If anything it would have to be "Android system", right now it's tied with the screen on 40%, but I charged the phone an hour ago and I haven't used the screen much.
Edit: I should add that the same thing just happened, from 99% to 89% then it stopped. That's why the information above about battery usage is relevant.
Do you think it might be hardware-related, like a partial short circuit or something, or is it most likely a software thing?
Bump. 10 signs.
Had mine for a few days, have not experienced anything like what you describe
I have though felt the screen get hot when turned on full brightness and reading a e-book on it (white - black text)
Well this is while it's laying in my pocket, with the screen off, so it's not the screen. (it's the battery that gets hot)
Take it back.
[Funny story that probably isn't relevant. I had a dodgy micro sd card that made my phone drain battery super fast and as a result my phone got incredibly hot. Took it out and it's back to normal.]
Sounds software related to me, your android system should definitely not be 40% of your battery. It sounds like some rogue app/process is utilizing your cpu and thus your battery very heavily. If you select the "Android system" in the battery usage list, does it not give you a further breakdown of what is included in that that is using your battery? Also, what does it say for the cpu time for the android system?
May be firmware bug
I've had this happen to me a few times when I was running the original firmware. In some early firmware there was a bug related to switching between wifi and 3G, which would get it stuck so that you couldn't toggle wifi on or off. The times this happened to me, it was also stuck in the wifi bug (although I had the wifi bug and it didn't drain the battery).
I now run the newer firmware (JG4) and both problems have stopped.
I've had this problem with my asian i9000 since the beginning. The app called Top showed me that it is ksoftirq/d that is running and System Panel showed me that the cpu was running at 100% at 1ghz.
At first the only solution seemed to be restarting the phone. However some information shared on this forum led me to try restarting wifi which also works. For that thread search for "ksoftirq/d."

I have had the "stuck wifi" bug, but I'm not sure if it was happening the last time this happened. I'll check it out the next time.
There's no official firmware update on Kies for Norway yet, so I think I'll wait for one.
Had exactly the same problem and tracked the culprit - it was Fancy widget in my case. Removed it, installed Beautiful widget and all is well since
Sent from my GT-I9000 using XDA App
That might actually be it. If I'm not mistaken Fancy Widget had 30% battery consumption when I checked. I deleted it just to see if it would make a difference. So far so good.
Some details:
Fancy Widget will hit the 100% cpu on auto-refresh if there's no data connection available (either wifi or cellular). It seems there are 2 bugs with Fancy Widget; it ignores "auto-refresh off" option and it tries to connect to server even when offline.
A dirty work around would be to set refresh time to let's say 12 hours and make sure to manually refresh at least once every
That makes me even more convinced that Fancy Widget is the culprit. I usually have cellular network disabled (APNDroid On/Off Widget) to save battery and my wifi connection keeps loosing connection, probably due to some software bug in XXJF3 stock firmware.
I don't know what all your experiences are, but I noticed the past few days that my epic is getting hot on the back.
I also noticed that my battery is draining more so than usual. When I got the update last week my battery life sucked, but now since this overheat thing it's gotten worse. It drops a lot even when in standby.
I do not have gps, wifi, anything else on. I am not rooted. Didn't do any battery tweaks. This is completely stock di18.
This is normal use with 3g. It's getting annoying and I'm hoping someone has an answer. Thanks!
Do you have any email accounts configured in the mail application?
This happened once or twice - I rebooted the phone and all was peachy.
Sounds like you have a rogue process wearin it out.
Yeah my phone overheated yesterday while charging....this phone has a few more steps to go before it really beats my hero...
Sent from my SPH-D700 using XDA App
I partly found out what the problem was, but it seems you guys are ahead of me. I had some process keeping my CPU running at 95-100% nonstop. I still haven't figured out what the process was, as now it is back to the normal 5-15%, but I'll have to keep an eye on it now.
the task manager widget turns red and it shows you what process was causing it...for me it was the xda app...a few times.
I think my problem was not backing out of WordFeud. I didn't notice anything on the task manager though. Hasn't happened since that one time.
this happens to me when i'm plugged in and using gmail. screen flickers and then shuts off. the screen-off battery indicator shows the batt. gauge and a little thermometer sign next to it indicating it's too hot.
wtf?!?! this has to be a defect. anyway, is there any official word on this? any pr from sammy/sprint?
i have read elsewhere about some epics resetting themselves a few times a day which could indicate an issue with heating (at least on a pc). so if you think it might be hardware its possible. otherwise keep doing what your doing, monitor your processes for anything thats eating it up, go to about phone > battery use > cell standby to see your time without signal. the higher this is the more battery use. also, might want to consider a startup manager to prevent the 2 DRM files (search forums) from running as this can affect batt life too
you can also use setcpu even (free on here, search it) to throttle your cpu down when it hits a certain temp.
This is very interesting... My wife and I both have this phone, she has had this happen several times after the last update (I though she was just crazy). Me on the other hand... No problem!
I need to look into this a little deeper.
The only time my epic's battery gets hot is during heavy use or gps. Gps/Nav makes it heat up like a mofo. But other than that... *knocks on wood* Its all good, no problems. As far at battery life, I am rooted and using SetCPU to turn down the processor while the screen is off, helps a ton. Not using anything other than that... was using juicedefender but then I started not getting calls or text...

One thing, I learned, that didn't help my battery was putting my phone in the locker at work. That thing must have killed my TWS and ate my battery alive.
i feel like this thread will start to die but i had a weird somewhat related issue last night. i too have had maybe 3-4 times where i woke up to my charging phone with the red LED and a screen that would not turn on, battery pull, worked fine.
however, THIS morning my phone would freeze like 30 seconds after boot EVERY time. tried a few things to no avail until I wiped, reinstalled my ROM (aosp 0.4.1) and the data from a previous backup (which was the way i got that ROM to first boot successfully according to tips in that thread).
so this worked, but i couldnt figure out why my other steps wouldnt. had to be something in the data partition of my system at the time, since changing that worked. the only thing i could think of is that app watchdog which someone mentioned to track processor usage by apps. anyone else ever experience this?
I have experienced this once when I was playing Robodefense while the phone was charging. My phone tends to get a little warm when it charges, and hot if I run something intensive while its charging. Wondering if this will be an issue when I use this phone for GPS nav while plugged into my car.

"I'm having this problem too...I didn't get any warranty for this either. Any reasons onto why this is happening...I woke up this morning and picked up my burning phone lol the temp was at 50C so I took out the battery and let it sit for 15 mins...it went down to 30C, then after not touching it for another 15..it was at 17C...very odd...what should I do, this crap is going to die within the next hour I'm worried it will fry the hard drive or something. Need help! " - I wrote this on a diff. forum a couple days ago
I dont have anything on, no wifi, gps, or any 4g (lol only if I could find it)...I even got rid of my facebook/twitter/weather updater widgets. The only thing that updates is email, and that's only if I click on it. The battery has been dying a lot faster and I charge my phone next to the window now because its like 20 degrees outside here in Chicago, so that brings down my phones temp lol....and today, my phone's battery life went from 100 to 5 percent in about three hours of barely using it...wtf?!
Also, another problem...sometimes when I lock my phone and unlock it after taking it out my pocket or something, the screen doesn't seem to respond...I keep swiping my finger over it to put in my password and it wont do anything and it only works when I slide up my phone for the horizontal view. This happens like 4 out of every 10 times I open phone.
Very embarrassing especially if your trying to get someones number down, I stopped showing off the phone now ...lol
So as it says, I am having a sudden issue with my battery. For the first few weeks after I bought this phone, I was sitting at nearly 2 full days before charging again. The past few weeks.. it has been decreasing steadily. From 2 full days to having to charge my phone every 1.5 days.. and now down to 1 day. This morning I wake up and my battery is being ridiculous. This was an overnight charge. I had only touched my phone last night to text and that was all.
I do not have have my phone rooted, and I would love to be able to fix the issue without rooting if possible! I really dislike losing all my game progresses when having to flash or factory reset anything.
As you can see in the attachment below.. I HAD great battery life. I played games frequently throughout the day.. used the phone quite often to text, facebook, chat on hangouts and still had 2 full days before needing to charge again.
Yes I've disabled a LOT of bloatware. I keep my location and bluetooth off at all times. I turned the WIFI from "Always on" to "Only when charging".I keep my screen brightness turned down and set to automatic. I turned off Google Search. I DO have motion gestures turned on, ONLY for the palm swipe screen capture.
I tried searching the forums for the answer and could not find one that directly applies to my issue. Most of them were short battery lives out of the box or shortened with the update in April.
I would appreciate any suggestions that you may have!
I'm in the exact same boat. When I went to bed last night my phone was at 27% and my device was dead when I woke up this morning.
I'm debating doing a factory reset on my phone, but that's a last resort.
I've had weird battery issues like this. Like 90% battery when I go to bed then the phone's off (2%) when I wake up. I've switched off the wi-fi toggles that we all know about but I also deleted and disabled most Samsung apps (except SHealth) and deleted the Samsung app store. I also got rid of all apps that I rarely or never use. This got rid of my battery issues and now have excellent battery life.
Yeah.. I have completely gutted out all the useless apps to me. That included all of Samsung's Apps and all but one T-mobile app. I'm in your boat Undergrad, I really don't want to factory reset if I don't need to!
I went into my Google Play and changed the updating from always to let me decide and turned off Google Search.
My battery still isn't where it used to be but that helped a lot. I'm now at 1d 2hours at 26%. The screen and Android System are neck and neck on my usage right now..
I wonder what app(s) is/are doing this.. maybe a recent update to them is just chunking away at our batteries.
Thank guys for letting me know I'm not alone!
For a month or more I'm facing totally unexplainable battery drain.
As seen on the screens below, the phone is awake, but it is not detected anywhere - not by android nor by GSam. In any case the battery draws faster.
I have one observation tho - this happens after I make phone calls. Not every time, but once per 2,3 days.
Any ideas?

You have this problem
http://forum.xda-developers.com/note-4/general/explanation-horrible-note-4-battery-t3004274
I'm pretty sure that I don't have this issue. Yes, the percentage in GSam maybe high, but I don't believe this reflects what is happening.
First of all - I don't have bad battery life. Usually my over night drain is less than 1%/1h.
Second - the issue appears sporadically.
Third - in the provided thread I don't see the issue appearing in stock battery monitor, while mine appear.
At last - my battery drains faster only while the issue is present and before I restart. After that it is back to normal ...
@Spo0f
Just some suggestions maybe you're using 3g I always have that turned off and switch it on when I use it my guess is that some apps are causing your drain after a call maybe like you said if you're not fimiliar with greenify I suggest you use it to stop all those apps and system apps also uninstall all those bloatware you don't need or at least freeze them if you don't mind lower the resolution to 1080p with nomone app use power save or disable dvfs and use an app to lower and raise the CPU to save juice when not needed....
Thanks for the suggestions, but as I said - this problem appear sporadically - home when using WiFi as well as outside when using 3G.
All of the rest is done - I'm no newby

Oh sorry mate well I don't use much 3g so I can't help you there but if you're having drainage when you're using WiFi in general then maybe you should reconsider investigating the post above with the link I don't have so much drainage on connectivity with 3g or WiFi....viewing the pics you uploaded it seems suspicious.... Maybe an app? I don't know...

My overnight drain was also very low, but that was because the faulty device on the network was asleep at night too (my desktop).
If you're not rooted, use the PC version of Wakelock Detector at the end of your day and post screenshots of your highest drainers for the various categories. In my case, the device was being woken up by something on the network and it showed.
Bear in mind that actively downloading something in the time period will also raise wifi power used but more stats will help.
The fact that you're still experiencing a lot of drain even when outside suggests it might be a rogue app
One phone call today and after it the phone stayed awake.
Because I had issue with the PC WLD the screen shots are from 11 minutes after one of the disconnects. The device was awake all of them.

I also checked out my battery behaviour this night and was very disappointed. Although my phone was in flight mode and every peripherals and services shut down, today morning my phone was crying for energy. So I made a quick investigation in my power diagram and found out, that "Android OS" requested a wakelock during the whole power-on time. So I installed "CPU Spy" to check in which states the phone was really over the whole charging period. I couldn't believe my eyes. Although the kernel should do it's job good, cause most of the CPU times are in lower freqeuncy states, the deep sleep mode was never activated.
Therefore I installed an app called "Wakelock Detector" to check out which apps could cause that. I found out, that S Health had a big amount of wakelocks and also active-time, so the first thing was to disable S Health. After some minutes I checked back, but nevertheless still no deep sleep time in "CPU Spy".
So I searched around and found another one arguing about the wakelocks and that they could be the products of some programming issues concerning WiFi. The should be gone, after turning off WiFi and rebooting yout phone. And it seems that he was right. I waited some time and hooray, "CPU Spy" listed the phone state "Deep Sleep" the first time as an active state and also with the major active-time. So at least that was some step ahead. (I have to remark, that S Health was already unfrozen at this time, so S Health should not be responsible in any way.)
The next step was to reactivate WiFi, leave it on and set the phone on standby. After some time I checked back again the phone showed even more deep sleep time. So that was an improvement. I reactivated everything and waited some time... Deep Sleep all over the time. Can't figure out for now, if it was S Health, WiFi, or anything else that caused the wakelock for sure. At least the reboot helped. I'll check that out on a long-term test, maybe I get some further conclusions.
